Receive Files from External Users with Thru Dropbox™
If you need to securely receive large files from users without a Thru account, you can create a link to your Thru Dropbox™ and make it available from email signatures, web portals, and anywhere that supports hyperlinks.
When users upload files to your Thru Dropbox™, you receive an email notification letting you know that they have dropped files in your Thru Dropbox™ folder.
